I worked in a PCB factory for about 2 years, and replacing SMDs was part of my job. The correct way to install a surface-mount electrolytic capacitor (as well as other types of SMDs) is to add a little solder to one of the pads, which you'll use to tack the capacitor in place. Then solder the leg that isn't tacked down, which will give you a proper solder joint on that leg, then reflow the solder on the tacked-down leg, which will give you a proper solder joint on that leg too. A small, angled, conical tip is ideal for installing SMDs. At work we used Metcal STSS and MX-500 solder stations with STTC-126 tip cartridges (I have the same setup at home too), along with 0.015" diameter Alpha Metals SMT Core Cleanline Plus 63/37 solder (P1 flux percentage) for tiny SMTs, and 0.020" diameter for through-hole components.
I got vigorous imagery of Louis Rossman talking to this poor motherboard about someone mistreating it with a hot iron and no solder when I was watching the episode. I have to admit, I think this is how most of us have things around here: a unregulated soldering iron from 80s or 90s and no flux. At least that's how things have been for me for years. Two damage that could have been avoided with flux and an iron at the proper temperature.
After watching Louis I discovered flux and now feel like I can solder SMT with loads of confidence now. And desoldering braid works soooooo much better with a little flux as well!

When soldering surface mount capacitors by hand, apply a SMALL amount of solder to one of the pcb pads. Hold the cap on the pads pressing down slightly and heat the pre-tinned pad to melt the solder, and seat the cap in place. Then solder the other lead. Finally, reflow the first lead with a bit of flux and you're done!

I've done the dishwasher trick, especially on expensive keyboards. A tip: regular tap water contains minerals, which once dry can create shorts. Do a final rinse in a tub of distilled water before drying.
Actually, it was a brief interlude. The original beige Macs were a nightmare to service, and they were designed to be. "Don't repair, repurchase!" was Jobs' theme song.
@@JimFortune That philosophy is still in use today by most manufacturers of consumer electronics. I'm glad that broken screens and dead batteries can be replaced on today's smartphones, hence that being all but easy to do.
Yep, that's leaked caps in the second power supply. That's just exactly what it looks like. Even the corrosion visible from the outside is caused by the caps. Had this happen to several Mac PSUs. You HAVE to replace them, especially the output filter caps. These are early low-ESR caps (early nichicon PL/PM series) which are notorious for leaking. And if the leakage didn't already spread over the whole board (and shielding), it might have accumulated UNDER the caps, where it functions as a conductor between the terminals of the cap. All the stuff you can see on the dead PSU is actually capacitor leakage. And another thing (yeah, there are many methods, i know): After taking it out of the dishwasher and removing leftover electrolyte, i would place the board into some distilled water for some time to dissolve any minerals from the tap water and invisible leftover electrolyte that stayed on the board.
Well, that's what the dishwasher tabs are for. It has acidic components so it should dissolve calcium carbonate from the water. Distilled water dissolve it sure, but when you put it out, that same water has to dry, making it leave the calcium on the board again.
I feel like every time I see 8-Bit Guy solder or desolder, I'm not only yelling FLUX DAMMIT FLUX, but I've now resorted to throwing flux at the screen.
@@cekpi7 It's great, but only helpful once solder starts flowing. You can see this highlighted at 2 points in the video. The first is when he's removing leads. The solder is very old and oxidized and on the second lead takes some effort to get enough heat transferred to melt the solder. A dab of flux when dealing with old solder makes things so much easier. The second is when adding on the new caps. You'll notice he tins the pads and the leads, this makes it much harder to install as the surfaces are uneven. He's doing it though because it distributes flux, it'd be much easier to add flux as it's own step instead of tinning everything.
@@russdill You are right, however if he added a bit of solder with flux to that old solder it would also work. Most of the time when i'm quickly trying to solder something i put component in place and just use solder with flux in it to solder it, not tinning each component before, this way surface is even and flux can reach both pcb and component at the same time. It's not wrong it just takes much more efford and time to do it right.
Actually there is a different methode to solder those smd parts. Remove the old solder from all pads, THEN pre tin only one pad. Put the part to solder on the pads and heat the one pad you pre tined. The part will sink into the solder. You can then solder each and every leg with standard solder with flux core. A needle tip and a 8 to 20 watt iron is warmly recommended for that technique.
TDK power supplies all go eventually tick-tock (literally!) when the secondary filter caps leak. I repaired about 30 of them, don't ask why. All of them needed just the capacitors, and I even started to recap them on sight even those which were still working. You did it almost 100% right, only concern would be that you missed two capacitors near the RAM slots. Also the corrosion around the legs of the small chips and the audio IC (the big chip in the left corner) is still present. I usually did a bulk recap of about 10 boards and put them all in dishwasher 2-3 cycles before soldering new capacitors. For the capacitors, I used tantalum ones at first, but when my stock of them dried up, I switched to ceramic ones and polymer for the values I couldn't get ceramics. Much better in the long run and they will not leak again! Few Mac systems that need recaps are: Mac SE/30, Mac II series, all Mac Classic series, PowerBook 100, PowerBook 100-140-160 LCD screens, PowerBook Power Bricks!, all LC and Performa series, all Quadras and all PowerMacs 6100, 7100, 7200, etc. PowerBook Duos, PowerBook Duo Docks, internal CD-ROM drives in Quadras and PowerMacs (especially those with external caddies), some internal floppy drives, and I am sure I missed a few. These are just the ones I remember fixing :) Yes, even the Power Macintosh models started to have capacitor issues :(
He removes those capacitors the same way my dentist removes teeth: a little twisting, a little tugging, a little more cranking and pulling, and then... voila!
Great result, David! I can confirm that the twisting cap method is effective. Also, I have washed many boards in a dishwasher with no adverse effects. I do remove the RAM and socketed chips to be safe. And dishwasher detergent is an effective method of cleaning ‘Cap Juice’ from boards. After the dishwashe, be sure to flush the boards with isopropyl alcohol and then deionised water to rinse any debris from the board. Airdusters are good to blow water from under chips and chip carriers. Compressor air is not a good source as it can contain moisture and unless it is properly earthed, may be damaged with ions in the compressor air. In work we place boards to be dried in an oven at 50° C for up to thirty minutes to drive out any moisture.
Protip: If your solder smokes briefly and intensely like in 7:22, then your iron is too hot! It should hardly be smoking at all. Protip 2: If your soldering iron does not have a temperature knob, you can use a lamp dimmer to regulate its power
Protip 3: Never get your hot soldering iron into that crud of chemistry on the board but clean up the whole thing *before* making it hot and doing aggressive reactions of all kind! It were the chemicals on the board and contacts that did get the whole thing into smoke in that case.
Power regulation instead of temperature regulation is just plain dumb and useless. You can get a solid T12-style soldering station for 30 bucks on aliexpress...
@@Diggnuts We have a fourth, known as "Sticky Kid". It's a sticky, gross... "material" that ends up everywhere. Can't ID- can't figure out how to exactly clean it- it stains *everything*...
Hi David, Not an expert by I do rework some boards. Get some $5 Hakko SMD tweezers from Amazon, makes holding parts while you solder so much easier. Also worth considering getting a cheap hot air rework station. That way you just heat up the part and the caps lift right off. You can then flux and solder the replacements way easier. I spent $250 on mine, but I've used $100 stations and they're fine for what you're doing.
Hot air is my choice for this kind of thing. Just have to be careful not to knock any of the other components out of place while doing it, but they're easy enough to put back if you do.
@mickelilltroll77 Normally, yes. But these surface mount electrolytics are just horrid little things. You end up melting the plastic base with the tweezers more often than not. Hot air all the way. Busting them with pliers can stress the PCB and lift pads very easily. At least cut them with some side snips if you're going to go medieval on them. That still has a risk of stressing the pads, but not as much.
My father-in-law works at a facility that has a particle accelerator. I took a tour of their electronics shop a few year's ago. They had a dish washer in the lab for washing circuit boards.
Nice restore, for those surface mount capacitors what I would recommend getting is some ceramic tweezers. Don't cost too much and small enough not to get in the way and the heat doesn't shoot up them due to their nature.
I think you left the kettle on the stove again (the whistling noise from the speaker sounded like the kettle going off). Or in CZcams auto gen captions: [Applause] [Music]
@KeeDx3 Get two temperature controlled soldering irons. If you only have one, check out the TS100, it is pretty cheap and pretty good (but keep in mind that it requires 12-24V DC power; You can easily convert an old laptop PSU for that). Apply fresh solder to both capacitor pads. Set the irons to maybe ~370 degrees C, take one iron in each hand, and heat up both pads simultaneously. When the solder is melted, simply tilt the irons up in order to lift the cap off the board. This is a very effective and gentle way of removing SMD caps, or any other two pin SMD component, IMHO.
@KeeDx3 Look up Voultar on CZcams, he does an excellent job showing the CORRECT technique which uses hot air and a soldering station. I did my old PC engine duo which has a crap ton of these caps and it now works flawlessly.
Here's mine: 1- Using a hot air SMT reflow workstation, it's easier to both unsolder old caps and resolder the new ones. I use a a Gordak 952 myself, but better / more suitable solder rework stations also exist. *[1] 3- Someone else already said it, but using more solder flux is always better and makes everything much easier! You can always remove the excess flux with some alcohol. 3- I'd say using a pair of precision tweezers instead of plyers is also a must. If you're interested, watch Voultar's videos. He makes pretty awesome tutorials for doing work on retro hardware :) However, I approve of The 8-bit Guys method of breaking the leads, it's a safe method and the only downside is the extra time it takes, and that soldering job might not turn out just as clean and professional. That doesn't really matter, as the final results definitely work well. *[1] - (EDIT: as multiple people already said, it may not be a good idea to use hot air with corroded pads (like here) as you might risk breaking them apart. TBH, I have never worked on a PCB with "cap juice" on them before, and I just wanted to share my experience with you.
@@cruiser1333 The problem with the hot air method when the pads and caps are this corroded it is very very hard to get the suckers to melt. You end up doing more damage. I have recapped dozens of boards and when they are this corroded cutting them off, in my experience, has been far more successful.
right. it took me 3 days to make that decission with my A2000 board. It worked well, looked like new. But I didnt use a tab and no heating/drying phase in the dishwasher. After that, water was displaced by alcohol (isopropanol), evaporates fast.
Safe? You seem to be a lucky guy, as sometimes it indeed can go horrible wrong. Dishwashers and water especially with cleaning tabs are a big no-no for cleaning of boards like everything treating electronics directly with water. Components are not hermetically sealed, water can creep below components and eating away modern BGA soldering balls/ contacts, it even can creep into the components itself eating away the pins, in some rare cases it can even get it's way up to the Dye itself! So, if you use a dishwasher, do it on your own risk!
I think a large ultrasonic tank would probably the most delicate way to clean boards. Distilled water, maybe with a bit of alcohol. But the usual ultrasonic cleaners are for small objects, like glasses. The dishwasher seems fine, but I guess you have to keep an eye on the temperature.
Oh, ok. This is news to me. I saw that Louis Rossmann puts all boards into a cleaner after a repair. But maybe vintage oscillators can break. However they should be something that can be more easily replaced. But it’s worrying.
Both are correct! Depends upon the caps themselves, their age, phase of the moon... Seriously, with different manufacturers and different production dates, it's hard to make a blanket statement. Don't forget to get quality replacements, or you'll be back in there replacing them again. Also, check out MikesRadioRepair CZcams channel. He talks about some adhesive that turns corrosive over time as it soaks up moisture from the air. It has a similar effect to the leaking electrolyte.
Recapping really never hurts when refurbishing electronics. For power supplies it makes them far less likely to kill boards, and for things like CRT monitors it can actually make the geometry a lot more consistent as well as fixing color issues. If it’s something you care about that you’d like to stick around for a while recapping it will cut out the most common point of failure on a large amount of tech.
@@Evildandalo Except sometimes you see really bad recap jobs where borderline unsuitable and suspicious caps have been used. Also when you install a new part, even if you don't use low-quality parts, sometimes you still can't be quite sure whether it's not a dud and whether it won't give up a short while later due to a latent defect, even if it reads fine at first sight. If they are through-hole, you lift up a leg, connect it to an LCR which measures ESR and leakage, and if it looks only slightly worse than a capacitor that is fresh out of the factory or exactly the same as one that spent just a couple years in storage, often the Nichicon caps you'll see in a C64 for example, well... if it has degraded this little in 30 years prior, it should be good to go for another 30, i see it as a lower risk just putting it straight back in. Also there's always a bit of a risk of damaging the board. I think it's best to ask around what the repair community consensus is, whether there are known issues with a particular product family or batch, and if there is a good possibility that there is, replace right away, otherwise, don't fix what isn't broken. Sometimes capacitors last less than 4 years, sometimes they are still perfect after 40, and it's dependent both on the capacitor, on the operating environment such as whether there are heat sources nearby, and on the circuit.
When pre-tinning small components I like to use some duct tape wrapped around itself sticky side out, then stuck to the working surface. If you want it tight wrap it around a small piece of cardboard. Works like a charm.
3:39 You should really use liquid flux and add fresh solder. 7:33 If you plan to do more SMD rework, you should get a hot air station. It makes soldering and removing SMD parts way easier.
@@slap_my_hand it's sort of 50/50 on the snapping leads vs hot air for removal, if the pads are in bad shape, sometimes the solder is holding everything together, of course since he didn't use flux or a well tinned tip it didn't make any difference anyways. Lots of flux and a hot air station (or hot tip tweezers) would have been the best way to remove the caps
I followed the same approach to remove the SMD caps as David on my Macintosh IIci and it worked great. I did the dishwasher trick as well. Now my Mac boots up and even has sound.
you can even use horse piss if you want....you just cannot unsolder one lead and tilt the component like you do on through hole because you WILL lift a trace...breaking them with sideways rotational motion is safe, effective and recommended and you can use flux but you do the same job without it.this not reballing a gpu or anything like that. and yes i do electronics work on a daily basis mainly automotive ecu's . also if you spend too much time with the iron either dessoldering or soldering them you will break the bond between the trace and the board, if both parts are tinned and you have a steady hand, one second dwell time is more than enough on each leg
There's allot of ways to pull corroded caps off s board without damaging it. But when it comes to flux there's only one way.......US FLUX! The flux in solder is good for one use then you start to get a cold solder joint. Once the solder can't flow you've got a shit joint. Simple as that.
@@animalyze7120 You need to be more educated then that. The flux in the solder is good for a single use and is only good for applications where you're dealing with two brand new surfaces. In this case you're dealing with a very old and corroded surface in which the cleaning properties in flux will not only clean the pads up further, but they'll allow the solder to flow to where it needs to go.
I am watching this video as I am preparing for recapping and installing FPU to my old LC II. Believe it or not dishwashers are not very common where I live, so I think I’ll have to scrub it a lot. I also bought some soldering flux to help me soldering the new capacitors.

That last part was very inspiring and really something crazy to think about. I have at least a few Macs in a storage unit that need love before it's too late!
90's SMD caps, our poor poor machines. I would have washed before desolder - those fumes... Dishwasher is great, careful with any labels you want to keep intact.
Thanks David.. In my experience, I add liquid flux to the de-solder braid it helps it work better. I prefer tweeters to hold down components. I clean where I soldered with Isopropyl alcohol after (de) soldering. Either way I'm glad you repaired it. Best wishes.
I agree with all your points. I would just add that when soldering the caps back on, tin only one of the pads before placing the cap, then solder only the one lead. After the one lead is soldered and the cap is in a good position, solder the other lead with extra solder.
Ah yes, Vette, you could run over a dozen pedestrians on the sidewalk, get pulled over by a cop, and say “but officer, I needed to find a bathroom… badly,” and he might just let you go.

@@TUUK2006 yeah, the problem is SALT. Which you literally have to put in your dishwasher. You have to wash the board with distilled water afterwards, otherwise god knows how much is the leftover salt going to corrode the board later on
Thanks for the inspiration! I just sent my Amiga 600 for recapping to a professional and he said there already was corrosion and leakage. He managed to repair everything, luckily.
Thanks for the advice on capacitors! I'll definitely be checking my ti 99/4a this week. Also, I definitely recommend getting an ultrasonic cleaner for your boards, rather than the dishwasher. They are specifically designed for electronics, and should clean the boards off entirely
I've not soldered SMD caps like you've done, but I have done many diodes for my mechanical keyboards. I use a pair of tweezers and a magnifying visor when I'm doing that kind of soldering. I do like the way you removed the caps and then the leads. Nicely done!
And if you do it right. @The 8-Bit Guy : Put flux on the PCB (and the cap if you will) Put solder only on one pad of the PCB Gently maintain the solder barely melt on the PCB while placing the cap with a set of tweezers When in place, remove the solder iron from the pad. The cap should be soldered in the correct spot. Now, solder the other pad, without stress. When done, you can reflow (remelt) your first solder to release tension. Sounds hard, but it's awfully simple in fact.
I used to be a body piercer , you should pick up some hemostats if you can find them! Can get them in quite a few different sizes to find the best fit for your hand, and at different lengths. They'd be perfect for those tiny pieces, i used them all the time for helping me screw on the threaded ends of jewelry in hard to reach ear piercings. I have big hands so that was always a pain spot for me lol love the videos man!
As much compressed air as you use, you should get a Datavac blower, or some other kind of compressor/blower. A hot air reflow station would help a lot with the SMD components too, both soldering and desoldering.
They make a little mini/micro hot air gun -- that is the ideal tool for desoldering and soldering tiny things like this. I saw it on some hard drive repair video a while ago. One tool I have for desoldering is a little popper vacuum pump thing. Works really great.
Great job on the restoration. Looks like a nice computer to have working! 6:40 the huge cap on the left looks to be bulging some. Anti-static brushes are allegedly safer than a toothbrush for cleaning...

The solder is very old and oxidized and on the second lead takes some effort to get enough heat transferred to melt the solder. A dab of flux when dealing with old solder makes things so much easier.
The second is when adding on the new caps. You'll notice he tins the pads and the leads, this makes it much harder to install as the surfaces are uneven. He's doing it though because it distributes flux, it'd be much easier to add flux as it's own step instead of tinning everything.
@@russdill You are right, however if he added a bit of solder with flux to that old solder it would also work. Most of the time when i'm quickly trying to solder something i put component in place and just use solder with flux in it to solder it, not tinning each component before, this way surface is even and flux can reach both pcb and component at the same time. It's not wrong it just takes much more efford and time to do it right.
Actually there is a different methode to solder those smd parts. Remove the old solder from all pads, THEN pre tin only one pad. Put the part to solder on the pads and heat the one pad you pre tined. The part will sink into the solder. You can then solder each and every leg with standard solder with flux core. A needle tip and a 8 to 20 watt iron is warmly recommended for that technique.
TDK power supplies all go eventually tick-tock (literally!) when the secondary filter caps leak. I repaired about 30 of them, don't ask why. All of them needed just the capacitors, and I even started to recap them on sight even those which were still working.
You did it almost 100% right, only concern would be that you missed two capacitors near the RAM slots. Also the corrosion around the legs of the small chips and the audio IC (the big chip in the left corner) is still present. I usually did a bulk recap of about 10 boards and put them all in dishwasher 2-3 cycles before soldering new capacitors.
For the capacitors, I used tantalum ones at first, but when my stock of them dried up, I switched to ceramic ones and polymer for the values I couldn't get ceramics. Much better in the long run and they will not leak again!
Few Mac systems that need recaps are: Mac SE/30, Mac II series, all Mac Classic series, PowerBook 100, PowerBook 100-140-160 LCD screens, PowerBook Power Bricks!, all LC and Performa series, all Quadras and all PowerMacs 6100, 7100, 7200, etc. PowerBook Duos, PowerBook Duo Docks, internal CD-ROM drives in Quadras and PowerMacs (especially those with external caddies), some internal floppy drives, and I am sure I missed a few. These are just the ones I remember fixing :) Yes, even the Power Macintosh models started to have capacitor issues :(
5:09 Louis Rossman just punched his desk into 2 after watching this. I personally loved the dishwasher
I was thinking the same exact thing!
Not even a nanopaul of flux. Such a disgusting practice of complete disrespect to that board. That's why those caps were near impossible to remove.
He was a supersonic washer...
@@xnagytibor You beat me to it, I was going to make a similar joke.
*Rossmann*
He removes those capacitors the same way my dentist removes teeth: a little twisting, a little tugging, a little more cranking and pulling, and then... voila!
You should change your specialist asap.
Your dentist should get a hot air station and some flux.
Where did you find your dentist, a 19th century frontier town?
i have yet to see a dentist that desolders teeth
How many teeth do you need removed, cleetus?
Great result, David!
I can confirm that the twisting cap method is effective.
Also, I have washed many boards in a dishwasher with no adverse effects.
I do remove the RAM and socketed chips to be safe.
And dishwasher detergent is an effective method of cleaning ‘Cap Juice’ from boards.
After the dishwashe, be sure to flush the boards with isopropyl alcohol and then deionised water to rinse any debris from the board.
Airdusters are good to blow water from under chips and chip carriers. Compressor air is not a good source as it can contain moisture and unless it is properly earthed, may be damaged with ions in the compressor air.
In work we place boards to be dried in an oven at 50° C for up to thirty minutes to drive out any moisture.
Protip: If your solder smokes briefly and intensely like in 7:22, then your iron is too hot! It should hardly be smoking at all.
Protip 2: If your soldering iron does not have a temperature knob, you can use a lamp dimmer to regulate its power
Thank you. Holy shit
Protip 3: Never get your hot soldering iron into that crud of chemistry on the board but clean up the whole thing *before* making it hot and doing aggressive reactions of all kind! It were the chemicals on the board and contacts that did get the whole thing into smoke in that case.
Power regulation instead of temperature regulation is just plain dumb and useless. You can get a solid T12-style soldering station for 30 bucks on aliexpress...

Tip: Please use Flux when you solder. It ensures a good solder joint and makes adhesion to the pads a lot easier.
A lot of solder has flux built-in
@@vinesthemonkey It does but it's still not as effective as adding more on the side. You can only fit that much flux inside the lead
The bigger the glob, the better the job.
Don't delay, flux those joints today!
Don't bother! you try and tell people who don't solder much to use the stuff and they never do, until months of crap joints hassle, then they get it!
he is using flux capacitors

Hi David,
Not an expert by I do rework some boards. Get some $5 Hakko SMD tweezers from Amazon, makes holding parts while you solder so much easier.
Also worth considering getting a cheap hot air rework station. That way you just heat up the part and the caps lift right off. You can then flux and solder the replacements way easier. I spent $250 on mine, but I've used $100 stations and they're fine for what you're doing.
Hot air is my choice for this kind of thing. Just have to be careful not to knock any of the other components out of place while doing it, but they're easy enough to put back if you do.
SMD tweezers are great when you do not want to heat the PCB with hot air!
@mickelilltroll77 Normally, yes. But these surface mount electrolytics are just horrid little things. You end up melting the plastic base with the tweezers more often than not. Hot air all the way. Busting them with pliers can stress the PCB and lift pads very easily. At least cut them with some side snips if you're going to go medieval on them. That still has a risk of stressing the pads, but not as much.
Michael Giacomelli Helping hands can help with smaller boards too.
00:29 what seems to be the problem?
"Well, my Mac screams on start."
My father-in-law works at a facility that has a particle accelerator. I took a tour of their electronics shop a few year's ago. They had a dish washer in the lab for washing circuit boards.
Nice restore, for those surface mount capacitors what I would recommend getting is some ceramic tweezers. Don't cost too much and small enough not to get in the way and the heat doesn't shoot up them due to their nature.
I think you left the kettle on the stove again (the whistling noise from the speaker sounded like the kettle going off).

“I guarantee that someone will say this in the comments, ‘Youre doing it wrong’”
I have to say this.
You’re doing it wrong
@KeeDx3 Get two temperature controlled soldering irons. If you only have one, check out the TS100, it is pretty cheap and pretty good (but keep in mind that it requires 12-24V DC power; You can easily convert an old laptop PSU for that). Apply fresh solder to both capacitor pads. Set the irons to maybe ~370 degrees C, take one iron in each hand, and heat up both pads simultaneously. When the solder is melted, simply tilt the irons up in order to lift the cap off the board. This is a very effective and gentle way of removing SMD caps, or any other two pin SMD component, IMHO.
@KeeDx3 Look up Voultar on CZcams, he does an excellent job showing the CORRECT technique which uses hot air and a soldering station. I did my old PC engine duo which has a crap ton of these caps and it now works flawlessly.
Here's mine:
1- Using a hot air SMT reflow workstation, it's easier to both unsolder old caps and resolder the new ones. I use a a Gordak 952 myself, but better / more suitable solder rework stations also exist. *[1]
3- Someone else already said it, but using more solder flux is always better and makes everything much easier! You can always remove the excess flux with some alcohol.
3- I'd say using a pair of precision tweezers instead of plyers is also a must.
If you're interested, watch Voultar's videos. He makes pretty awesome tutorials for doing work on retro hardware :)
However, I approve of The 8-bit Guys method of breaking the leads, it's a safe method and the only downside is the extra time it takes, and that soldering job might not turn out just as clean and professional. That doesn't really matter, as the final results definitely work well.
*[1] - (EDIT: as multiple people already said, it may not be a good idea to use hot air with corroded pads (like here) as you might risk breaking them apart. TBH, I have never worked on a PCB with "cap juice" on them before, and I just wanted to share my experience with you.
@@cruiser1333 The problem with the hot air method when the pads and caps are this corroded it is very very hard to get the suckers to melt. You end up doing more damage. I have recapped dozens of boards and when they are this corroded cutting them off, in my experience, has been far more successful.
damn, I get the same reply when I'm wiping my ass.
I know it's safe to wash a motherboard in the dishwasher....
but it still FEELS wrong.
right. it took me 3 days to make that decission with my A2000 board. It worked well, looked like new. But I didnt use a tab and no heating/drying phase in the dishwasher. After that, water was displaced by alcohol (isopropanol), evaporates fast.
Safe? You seem to be a lucky guy, as sometimes it indeed can go horrible wrong. Dishwashers and water especially with cleaning tabs are a big no-no for cleaning of boards like everything treating electronics directly with water. Components are not hermetically sealed, water can creep below components and eating away modern BGA soldering balls/ contacts, it even can creep into the components itself eating away the pins, in some rare cases it can even get it's way up to the Dye itself! So, if you use a dishwasher, do it on your own risk!
Well done! At 6:41 the big cap does look a bit blown up on the top, though...
this resto is one of my all time video series by the 8-Bit Guy. Hardest working and most motivated CZcamsr I've ever watched
I think a large ultrasonic tank would probably the most delicate way to clean boards. Distilled water, maybe with a bit of alcohol. But the usual ultrasonic cleaners are for small objects, like glasses. The dishwasher seems fine, but I guess you have to keep an eye on the temperature.
I have found in the past that ultrasonic cleaning can damage crystal oscillators, so I'm wary of what I put in them.
Oh, ok. This is news to me. I saw that Louis Rossmann puts all boards into a cleaner after a repair. But maybe vintage oscillators can break. However they should be something that can be more easily replaced. But it’s worrying.
Techmoan: people will say I need to replace the caps in that. But I don’t need too
8 bit guy: I do need to replace the caps in that
Both are correct! Depends upon the caps themselves, their age, phase of the moon...
Seriously, with different manufacturers and different production dates, it's hard to make a blanket statement. Don't forget to get quality replacements, or you'll be back in there replacing them again.
Also, check out MikesRadioRepair CZcams channel. He talks about some adhesive that turns corrosive over time as it soaks up moisture from the air. It has a similar effect to the leaking electrolyte.
Recapping really never hurts when refurbishing electronics. For power supplies it makes them far less likely to kill boards, and for things like CRT monitors it can actually make the geometry a lot more consistent as well as fixing color issues. If it’s something you care about that you’d like to stick around for a while recapping it will cut out the most common point of failure on a large amount of tech.
@@Evildandalo Except sometimes you see really bad recap jobs where borderline unsuitable and suspicious caps have been used. Also when you install a new part, even if you don't use low-quality parts, sometimes you still can't be quite sure whether it's not a dud and whether it won't give up a short while later due to a latent defect, even if it reads fine at first sight. If they are through-hole, you lift up a leg, connect it to an LCR which measures ESR and leakage, and if it looks only slightly worse than a capacitor that is fresh out of the factory or exactly the same as one that spent just a couple years in storage, often the Nichicon caps you'll see in a C64 for example, well... if it has degraded this little in 30 years prior, it should be good to go for another 30, i see it as a lower risk just putting it straight back in.
Also there's always a bit of a risk of damaging the board. I think it's best to ask around what the repair community consensus is, whether there are known issues with a particular product family or batch, and if there is a good possibility that there is, replace right away, otherwise, don't fix what isn't broken. Sometimes capacitors last less than 4 years, sometimes they are still perfect after 40, and it's dependent both on the capacitor, on the operating environment such as whether there are heat sources nearby, and on the circuit.
I really enjoy your videos. These items speak directly to my childhood. Thank you for this amazing content.
When pre-tinning small components I like to use some duct tape wrapped around itself sticky side out, then stuck to the working surface. If you want it tight wrap it around a small piece of cardboard. Works like a charm.
Louis Rossman recommends 2 parts flux to 1 part PCB. It works every time.
The Right Amount of Flux
I thought he uses 1 tube of flux to 1 cap.
gotta have a happy little flux application
@@scottlloyd9762 that's a picoPaul of Flux
3:39 You should really use liquid flux and add fresh solder.
7:33 If you plan to do more SMD rework, you should get a hot air station. It makes soldering and removing SMD parts way easier.
He already has a decent station, so I think a separate hot air station is more than enough
Wrong. On both counts.
@ Care to explain why?
@@slap_my_hand it's sort of 50/50 on the snapping leads vs hot air for removal, if the pads are in bad shape, sometimes the solder is holding everything together, of course since he didn't use flux or a well tinned tip it didn't make any difference anyways. Lots of flux and a hot air station (or hot tip tweezers) would have been the best way to remove the caps
Very cool stuff. You brought me back in time to my years as a certified apple tech in the late 90s. :)
I followed the same approach to remove the SMD caps as David on my Macintosh IIci and it worked great. I did the dishwasher trick as well. Now my Mac boots up and even has sound.
everybody:
8bitguy: I Bet You'll Argue About Which Way To Pull Caps Off A Board Is The Wrong Way
everybody:
everybody: use flux tho
you can even use horse piss if you want....you just cannot unsolder one lead and tilt the component like you do on through hole because you WILL lift a trace...breaking them with sideways rotational motion is safe, effective and recommended and you can use flux but you do the same job without it.this not reballing a gpu or anything like that. and yes i do electronics work on a daily basis mainly automotive ecu's . also if you spend too much time with the iron either dessoldering or soldering them you will break the bond between the trace and the board, if both parts are tinned and you have a steady hand, one second dwell time is more than enough on each leg
You mean like flux already present in the solder he's using? Flux core. Seriously people it's not that complicated.
@@animalyze7120 flux is important. see all the other comments.
There's allot of ways to pull corroded caps off s board without damaging it. But when it comes to flux there's only one way.......US FLUX! The flux in solder is good for one use then you start to get a cold solder joint. Once the solder can't flow you've got a shit joint. Simple as that.
@@animalyze7120 You need to be more educated then that. The flux in the solder is good for a single use and is only good for applications where you're dealing with two brand new surfaces. In this case you're dealing with a very old and corroded surface in which the cleaning properties in flux will not only clean the pads up further, but they'll allow the solder to flow to where it needs to go.
Great video! A very satisfying watch!
I am watching this video as I am preparing for recapping and installing FPU to my old LC II. Believe it or not dishwashers are not very common where I live, so I think I’ll have to scrub it a lot. I also bought some soldering flux to help me soldering the new capacitors.

90's SMD caps, our poor poor machines. I would have washed before desolder - those fumes...
Dishwasher is great, careful with any labels you want to keep intact.
Thanks David.. In my experience, I add liquid flux to the de-solder braid it helps it work better. I prefer tweeters to hold down components. I clean where I soldered with Isopropyl alcohol after (de) soldering. Either way I'm glad you repaired it. Best wishes.
I agree with all your points. I would just add that when soldering the caps back on, tin only one of the pads before placing the cap, then solder only the one lead. After the one lead is soldered and the cap is in a good position, solder the other lead with extra solder.

Closing in on a million subscribers. Well done sir, well done.
*Speaker screeches* CZcams captions: *applause music* lol
Soldering SMD is a lot easier when you use the correct tools.
And if you do it right.
@The 8-Bit Guy :
Put flux on the PCB (and the cap if you will)
Put solder only on one pad of the PCB
Gently maintain the solder barely melt on the PCB while placing the cap with a set of tweezers
When in place, remove the solder iron from the pad. The cap should be soldered in the correct spot.
Now, solder the other pad, without stress.
When done, you can reflow (remelt) your first solder to release tension.
Sounds hard, but it's awfully simple in fact.
That was a fine solder job. Also, the dishwasher is so much more useful than I thought :)
I used to be a body piercer , you should pick up some hemostats if you can find them! Can get them in quite a few different sizes to find the best fit for your hand, and at different lengths. They'd be perfect for those tiny pieces, i used them all the time for helping me screw on the threaded ends of jewelry in hard to reach ear piercings. I have big hands so that was always a pain spot for me lol love the videos man!
"Anyway, that's it for the moment..." Reminded me of another of my favorite CZcamsrs, Techmoan. lol
Tech moans one his favs too
As much compressed air as you use, you should get a Datavac blower, or some other kind of compressor/blower.
A hot air reflow station would help a lot with the SMD components too, both soldering and desoldering.
Fantastic video as always!
They make a little mini/micro hot air gun -- that is the ideal tool for desoldering and soldering tiny things like this. I saw it on some hard drive repair video a while ago. One tool I have for desoldering is a little popper vacuum pump thing. Works really great.
